Forte Enterprise is now in production and accessible through IonQ Quantum Cloud and Amazon Braket; Tempo’s #AQ64 figure was an anticipated target, not a delivered specification. The announcement’s significance was its data-center form factor—not evidence that these machines replace classical computers for everyday workloads.
What IonQ unveiled—and what changed
On September 27, 2023, IonQ announced Forte Enterprise and Tempo as enterprise-grade trapped-ion quantum computers designed for rack-mounted deployment alongside conventional data-center equipment. The announcement positioned Forte Enterprise as a system targeting #AQ35 and Tempo as a future system anticipated to reach #AQ64.
The practical change was the physical packaging. IEEE Spectrum reported that Forte Enterprise was designed for roughly eight standard server cabinets and Tempo for three. These are cabinet-scale systems, not single-server appliances: rack mounting makes integration with data-center infrastructure more plausible, but does not make the computers small or simple to operate.
IonQ CEO Peter Chapman described the goal as building high-performance machines while “reducing the cost of every generation.” IonQ also said the systems would work alongside existing data-center hardware. That describes the intended deployment direction; it is not proof that either machine delivers a commercial advantage on a particular workload.

Forte Enterprise and Tempo compared
| Category | Forte Enterprise | Tempo |
|---|---|---|
| Algorithmic-qubit performance | #AQ35 target in IonQ’s September 2023 announcement; IonQ reported #AQ36 for the production system in April 2025. | #AQ64 anticipated in IonQ’s September 2023 announcement; this was a roadmap figure, not a delivered performance result. |
| Reported footprint | Roughly eight standard server cabinets, according to IEEE Spectrum’s 2023 report. | Three standard server cabinets, according to IEEE Spectrum’s 2023 report. |
| Deployment and environment | Designed for data-center integration. IonQ’s 2025 production announcement described lower energy consumption and lower environmental-isolation requirements for modern data centers. Specific facility requirements were not stated. | Designed for rack deployment and data-center integration; specific energy, isolation, or facility requirements were not stated in the cited announcement and report. |
| Access and availability | Commissioned and globally available in production as of IonQ’s April 1, 2025 announcement through IonQ Quantum Cloud and Amazon Braket. The cited announcement does not establish general on-premises purchasing terms. | Presented in 2023 as an anticipated future system. The cited material does not establish production availability or a customer-access route. |
| How to interpret the status | Production system; #AQ36 was the performance reported in 2025. | Roadmap projection; #AQ64 was anticipated, not confirmed as achieved. |
IEEE Spectrum also reported that Forte Enterprise was about 40% smaller than the previous Forte form factor. That comparison concerns the system’s size, not its computing performance.
What “rack-mounted” means for a quantum computer
IonQ’s systems use ytterbium ions held in place by electromagnetic fields and controlled with lasers. In its 2023 reporting, IEEE Spectrum described a redesign that replaced large optical assemblies with micro-optics and silicon photonics to fit a 19-inch-wide server-cabinet format. Rack compatibility therefore reflects substantial engineering of the optical and control systems; it does not mean the device works like an ordinary server that can be installed in a spare rack slot.
The 2025 Forte Enterprise announcement described lower energy consumption and lower environmental-isolation requirements for modern data centers. That is a relative description, not a complete facilities specification: the cited material does not give power, cooling, room, or installation figures a prospective host could use as a build sheet.
What #AQ35, #AQ36 and #AQ64 tell you
#AQ means algorithmic qubits, IonQ’s measure of qubits it says can be put to useful work. It is not a raw count of the physical qubits in the machine. The figures should be read with their dates and status attached: Forte Enterprise was announced with a #AQ35 target in 2023, and IonQ reported #AQ36 for the commissioned production system in 2025; Tempo’s #AQ64 was an anticipated 2023 figure.
IonQ claimed in 2023 that an #AQ64 Tempo system would have a computational space 536 million times larger than Forte Enterprise. That is IonQ’s comparison based on the anticipated #AQ64 figure, not an independent measurement of a delivered Tempo system or a guarantee of a corresponding speed-up for a customer’s application. Algorithmic-qubit measures do not by themselves establish that a specific workload will run faster or more cheaply than its classical alternative.
Can customers use Forte Enterprise now?
Yes. IonQ announced on April 1, 2025 that Forte Enterprise had been commissioned and was globally available in production through Amazon Braket, AWS’s managed quantum-computing service, and IonQ Quantum Cloud, IonQ’s direct cloud route. That establishes production access through those services; it does not establish that every customer can buy or install a physical system on premises.
- Amazon Braket: a managed AWS service for accessing Forte Enterprise.
- IonQ Quantum Cloud: IonQ’s direct first-party access route.
Cloud access is a practical starting point for teams that want to develop or evaluate workloads without hosting the rack-scale system. Whether cloud access is suitable depends on the application and service conditions: teams that require dedicated, predictable low-latency access should verify queueing, access, and deployment terms with the provider rather than assume those properties from the production announcement.

IonQ named process optimization, quantum machine learning, correlation analysis, and pattern recognition as target areas for Forte Enterprise. These are areas to investigate, not demonstrated wins over classical systems. IEEE Spectrum characterized Forte Enterprise as essentially a research platform intended to help customers develop applications for Tempo, rather than a proven replacement for classical computers across ordinary workloads.

A useful evaluation should begin with a concrete problem and a classical baseline. Teams need to determine whether the quantum formulation fits the hardware and whether results justify the costs and operational trade-offs. The announcements cited here do not supply workload-specific benchmark results, so they cannot establish that Forte Enterprise or Tempo is advantageous for a particular organization.
How the roadmap has moved on
IonQ announced Superion 256 on September 8, 2026. IonQ says the system uses a standard server-rack footprint, is accepting orders, and is planned for customer delivery in 2027. Those are company statements about a newly announced product: delivery remains forward-looking, and the announcement’s scaling and fault-tolerance claims should be treated as projections rather than achieved customer outcomes.
Superion 256 is a later step in IonQ’s rack-scale roadmap; it does not change the status distinction between production Forte Enterprise and the anticipated Tempo performance described in 2023. Nor does a rack footprint alone show that the system will be commercially useful for a given workload.
